One Direction Needs 100 Security Guards!

One Direction needed an army to protect them from their screaming fans for their debut in Dallas Saturday. The British boy band had almost 100 security guards taking care of them as they played for only 45 minutes at Dr. Pepper Ballpark. It seems that Justin Bieber better watch his back.

One Direction are the first band from the UK to debut at number one on the charts with their first album.

TMZ has an exclusive report: There are five members in the hit British boy band One Direction — and today in Dallas, there will be 20 security personnel for each of them … to ensure their rabid fan base stays safe and in check.

According to our sources, a security team of 100 has been assigned to protect the group for their performance … which is only supposed to last 45 minutes.

The band, which became the first UK group in history to debut at number one with their first album, is scheduled to play just four songs for a crowd of about 7,000 at the Dr Pepper Ballpark.

The security breaks down like this: 40 for close protection security, 50 more for the venue, and then 10 more just on stand by.

Your move, Bieber.

Do you think that One Direction’s rise is a harbinger of Justin Bieber’s decline? Can the teen market sustain two mega stars simultaneously – or will we see Justin on DWTS soon…
